INKING-ROLLER.

PECIFICATION formingpart of Letters Patent No. 741,275, dated October 13, 1903.

Application led September 4, 1902. Serial No. 122,025. (No model To all whom t may concern:

Be it known that I, JOSEPH J. RAETER, a citizen of the United States, residing in Hartford, in the county of I-Iartford and State of Connecticut, have invented certain new and useful Improvements in Inking-Rollers, of which the following is a specification'.

This invention relates to inkingrollers, and has for its object to provide an improved roller which may be removed from the spindle.

Another object of the invention is to provide means for mounting two or more rollers upon a spindle. p

Another object of the invention is to provide interrupted rollers for multicolor printing.

Another object of the invention is to provide means whereby rollers may be cast separate from the spindle and mounted thereon at will.

Heretofore printing-rollers, which are generally made from some plastic material, have been cast upon the spindle, thus making it necessary for the printer to have several spindles and ship the spindles to the roller-maker to cast the rollers upon them. It has also been the practice in printing several colors to run the work through the presses for every color. My invention contemplates casting or otherwise forming the ink or color receiving and distributing rollers separate and apart from the spindles or journals in such manner that they may be readily mounted upon and removed from the spindle or other journals and in any length, whereby one or more rollers may be placed upon a spindle, the length of the rollers to be determined by requirements of practice.

In the drawings accompanying and forming part of this specification, Figure l shows a form of my invention wherein there are two equal-sized rollers mounted upon a spindle and spaced apart. Fig. 2 is a similar view showing rollers of dissimilar lengths and broadly spaced, certain portions in each instance being shown in central vertical section. Fig. 3 is a perspective view of the end by A) in the present instance is shown as comprising a body portion Or shaft '7, with journals 8 at each end, and the rollers or ink receiving and distributing bodies (designated in a general way by B) comprise a body portion 9, made of any suitable material for receiving and distributing ink or other material which it is desired to apply in a similar manner. The rollers are cast or formed separate and apart from the spindle and, if desired, may be made upon a tube or sleeve ld, which in the present instance is shown as having a working fit with the body portion of the spindle. For ordinary work a single roller occupying any desired amount of the spindle may be mounted thereon and held, if desired, in such a manner as to compel it to rotate with the spindle by any suitable means, (here shown as a pin ll, passing through the spindle, which pin may engage suitable notches or lugs in the tube) or if the rollers are cast without tubes notches or lugs may be provided in or upon the rollers themselves, and for the purpose of conveniently removing the rollers a cotter-pin l2 may be provided yfor engaging the other end of the roller. Any suitable key or fastening device found desirablein practice may be employed at the ends. In Fig. l two rollers are shown as mounted upon a spindle in the manner described, and between the rollers is a tube 13, so disposed relatively to the rollers that it will in the present instance engage the tubes l0 upon which the rollers are cast and space them apart. Ifl it should be desired with the device made as shown in Fig. l to employ a roller equal to the length of both of the sections of roller, it will merely be necessary to draw the Cotter-pin and remove the roller and spacer-tube and change the places of the tube and the4 roller, thus bringing the tube 13 next the Cotter-pin and the ends of the rollers abutting. Th us a continuous roller will be had. In Fig. 2 the rollers are shown as of dissimilar lengths, which will be convenient in cases where it is desired to do printing in one color with a smaller amount of printing IOO of a dierent color; but it will not be necessary to use rollers of the same length for each color. In this instance, however, the end pin is shown as pressing into the roller to engage a notch in the tube, thus presenting a flush-ended roller.

rIt may be desired in practiceto hold the rollers merely from a pin at one end, in which instance a lock should be had between the rollers and the scraper. A convenient'form for so doing is illustrated in Figs. 3 and 4.

The tubes upon which the rollers are mounted or cast and also the spacing-tube may be made at their ends as illustrated at Fig. 4, wherein the tube 13 is shown as having notches 14 at one end and lugs or projections l5 at the other end adapted to mate with similarly-formedl tubes. Thus it will be seen that the notch of the roller may be caused to engage a stationary pin, either a spacer or a roller, put on the spindle and caused to have its notches engage the lugs, and so on until the spindle is filled, a Cotter-pin engaging the lugs or projections upon the last roller.

Although the rollers'have been shown as formed upon tubes and these mounted upon a spindle, yet it will be apparent that many other forms of construction. may be adapted to produce the same result without departing from my invention, and other devices may also be employed for holding the rollers stationary upon the spindle.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a spindle provided with a pin at one end; a roller cast yupon a tube having a working t with the spindle; notches in the end of the tube to engage the pin; lugs protruding from the opposite end of the tube; a spacer provided with similar notches and lugs; a roller similar to the first mounted upon the spindle and engaging the lugs of the spacer; and a cotter-pin engaging the lugs of the second roller.

2. The combination with a plurality of hollow cores, of a plurality of plastic rolls each cast upon one of the cores; a spindle with which the cores have a working tit and upon which they are mounted; aninterchangeable collar having a Working fit with the spindle and mouniedthereon between the cores; theY fit with the spindle and mounted thereon between the rolls; mating notches and lugs carried by the abutting ends of thefcores and collar and organized to lock the same from independent angular movement upon the spindle; and means for locking the cores to the spindle.
